... registers available, these variables are allocated either in the fixed area (for global variables) or on the program stack (for local variables). Automatic Variables Automatic variables are local variables ... management resolves this problem by allocating and reallocating memory dynamically. When the data set fills all available space in the array, we allocate a larger array file://///A...

... constructor passes to it its own parameter, character array; and the copy constructor passes to allocate() its parameter's character array s.str. When one object initializes another object, a copy ... argued against passing objects to functions as value parameters or as pointer parameters and promoted passing parameters by reference instead. I explained that pass by reference is al...

A good way to achieve that is to define class Stack as a template and then define class Node as a regular non-template class that ... object code. Instead of heap memory allocated at instantiation (or at array overflow), the Stack class can allocate a Node object every time data is pushed on the stack and deallocate the...
